1
What
scale measures the hardness
of a mineral?
Ritcher scale
Modified Mercalli scale
Mohs Hardness scale
Moment Magnitude scale
2
The
three main layers of Earth
are:
the rocks, mantle, and the core
the crust, the mantle, and the center
the crust, the mantle, and the core
the crust, the ocean, and the core
3
How does
RUNNING or flowing water affect mountains
?
It act is a destructive force that builds up the mountain.
It is a constructive force that builds up mountains.
It is a destructive force as it weathers and erodes rock.
It is a constructive force as it weathers and erodes rock.
4
Why are
minerals
that are made of the same
elements identified as different minerals
?
They are different sizes.
There is NO difference.
They were found in different locations.
Each has different amounts of the elements
5
What
provides the force that causes magma to erupt
to the surface?
silica in the magma
gravity in the lithosphere
dissolved gases trapped in the magma
the density of the magma
6
How do
tectonic plates interact with eachother
?
They collide, move apart and slip past other plates.
Plates can pull or move apart from other plates.
Plates collide with other plates.
Plates can slide past each other.
7
When scientists
use their 5 senses to gather information:
drawing a conclusion
making an observation
making an inference
predicting an outcome
8
A
rock that has large crystals
was formed:
from magma slowly cooling inside the earth
from lava quickly cooling
from other rocks and was changed by heat and pressure
from sediments being deposited, compacted and cemented
9
What is the
independent variable in an experiment
?
variable you change on purpose
variable that responds to the change you made
variable to which nothing is done
variable that you keep the same
10
What is the
major cause for the changes in shape and location of the continents and oceans
?
deposition
Volcanic eruptions
plate tectonics
gravity
11
What determines
how rocks are classified
?
According to their origin, or how they formed
According to the minerals present
according to their color
According to the amount of weathering
12
If a
volcano's magma is high in silica content
, then what
type of eruption
will it have?
oozing eruption
explosive eruption
extinct eruption
quiet eruption
13
Scientists often repeat experiments
multiple times because:
It allows them to test different variables.
It gives them something to do.
Several trials helps verify the results.
It then turns your hypothesis into a theory.
14
Earthquake waves travel at different speeds through parts of the Earth
because:
erosion of rock layers
time of earthquake wave
how many earthquakes that occur in an area
material that makes up the layer
15
What happens when
diamond
(hardest mineral)
rubs calcite
(lower hardness rating)?
The diamond will scratch the calcite.
It will create a spark.
Calcite will scratch the diamond.
Nothing will happen.
16
Which causes the
most change to SOLID Earth
?
the water cycle
ocean currents
the rock cycle
atmospheric convection
17
What
places on Earth are more likely to have earthquakes (and volcanoes)
?
regions where the tectonic plates meet
regions in the northern hemisphere
big cities
desert regions
18
Why is the
sun's energy
important to the
biosphere
?
The sun's energy creates water vapor.
The sun's energy heats the inner core of the Earth.
The sun provides energy for plants to grow.
The sun does not provide energy to the biosphere.
19
Variables
that are
kept the same
in an experiment:
hypothesis
conclusions
constants
controls
20
